So I own a 2015 dodge Challenger Scat Pack no mufflers or resonators and I recently went to a muffler shop to go get my exhaust fixed. I had a rattling in my exhaust and they told me they were my valves. I don’t know exactly what they did but it fixed the issue. But the next day I woke up for work and turned my car on and while I was driving, my check engine light came on which was the codes p1217 and p121b. I searched it up and that the codes meant active exhaust valve 1 performance and active exhaust valve performance 2. I called them after work and they told me that it’s my valves and they I need to buy new ones and they’ll install them for me and replace the old ones. I want to make sure that I’m buying the right part and would anyone know what part exactly it would be. I’ve been searching on the internet but I can’t exactly find any. Is it the whole valve actuator or just the active exhaust valve replacement?

On the sites I have been checking, they both show as backordered......

I can find delete kits for them everywhere though. I assume that removes the valves completely, so your exhaust is always "loud"....

 

Right. I did check mopar and saw they are on backorder. I do have my valves I see but they are loose and I can just move them around. Would I have to buy the full valve actuator. They pretty pricey.

 

I would be tempted to go for the delete kit. I don't know enough about the vales to know if they are repairable or not.
